APPARATUS FOR CARBONATING AND DISPENSING GINGER-ALE.

SPECIFICATION formingpart of Letters Patent No. 715,687, dated December 9, 1902.

Application filed January 13, 1902.

T0 aZZ whom, it may concern:

Be it known that I, AUSTIN R. PHILLIPS, a citizen of the United States, residing at O0- runna, in the'county of Shiawassee, State of Michigan, have invented certain new and useful Improvements in Apparatus for Carbonating and Dispensing Ginger-Ale; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to apparatus for carbonating and dispensing ginger-ale; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to produce an apparatus of the character described in which the arrangement is such as to enable ginger-ale to be carbonated in and drawn from an ordinary cask or beer-keg, obviating the use of an expensive tank adapted to resist a high pressure and enabling a thorough carbonation of the beverage with an exceedingly low pressure, effecting a material saving in the cost of the apparatus and economy in the use of gas. 1

The above object is attained by the combination and association of parts illustrated in the accompanying drawings, in which Figure 1 is a general view illustrating the application of my invention for use in drawing ginger-ale in saloon trade. Fig. 2 is an elevation of the bung and, sleeve with the inner tube inserted therein. Fig. 3 is a sectional view through a keg and the bung and sleeve, showing in elevation the inner tube within said sleeve and passing through said bung. Fig. 4 is an enlarged sectional view in detail of the bun g and sleeve and the inner tube partially withdrawn therefrom.

Referring to the characters of reference, 1 designates a keg of the ordinary type for containing beer, in which the ginger-ale or other beverage to be drawn is placed. In the head 2 of said keg is inserted a bung 3, having formed integral therewith a depending sleeve 4, which extends into the keg to a point near the bottom thereof. Located in the side of Serial No. 89.418. (N0 model.

the tube when desired. Attached to the up- I per end of the tube 9 is a pipe 12, which leads upwardly through the floor to a suitable cooling-coil13, located in the ice-box 14. From said cooling-coil a pipe 15 leads to the draftfauoet 16, whereby the beverage from the keg passes through the cooling-coil before it is drawn, which arrangement is common and well understood in the art.

At the upper end of the bung 3 is a compressible gasket 17, through which the inner tube 9 passes and which is compressed around said tube by the'gland 18, which screws intd the upper end of said-bung.

In placing this apparatus in position the sleeve 4 of the bung is passed through the bunghole of the keg, and the bung is made firm in said hole by driving'or other suitable means. The tube 9 is then passed downwardly through the bung and sleeve, as shown in Fig. 3, and is secured centrally in position by means of the gland 18, thereby forming a gas-chamber 19 within said bung and a gas passage-way 20, extending downwardly from said chamber between the sleeve 4 and the tube 9. This gas space or passage-way 20 terminates at the lower end of the sleeve 4: adjacent to the openings 10 in the bottom of the tube 9. By this arrangement the gas is discharged into the beverage of the cask at the bottom thereof and passes upwardly through said beverage, which absorbs said gas, and whereby it becomes carbonated. By introd ucing the carbonic-acid gas at the bottom of the cask said beverage becomes much more readily carbonated than where the gas is introduced at the top and is mingled with the beverage by agitation. The introduction of the gas at the bottom of the keg enables the beverage to be carbonated under a much lower pressure, for the reason that it more readily mingles with the beverage when introduced at that point, obviating the use of an expensive metallic cask necessary to hold the beverage where it is carbonated under a high gas-pressure. The point of the discharge of the gas from the passage-way 20 being adjacent to the intake-openings 10 at the bottom of the tube 9, the gas is discharged into said openings when a quantity of the beverage is drawn off, so that at any time the beverage is drawn, even in a small quantity, it is thoroughly permeated with gas. It will be understood that the pressure of the gas in the chamber 19 and the passage-way 20 is such as to force the liquid therefrom, so that the gas is continually on the point of discharging from the lower end of the sleeve and does discharge therefrom whenever the pressure in the keg is reduced by the operation of drawing the beverage.

The gas-pressure is so low under which the beverage is carbonated by the use of this apparatus that a common keg may be readily employed, and by means of this structure the parts may be readily cleaned, as the tube 9 may be easily withdrawn from the sleeve 4: and the bung with which said sleeve is attached. All the gaspressure that is required is sufficient only to force the beverage from the keg up to the draft-faucet and discharge it therefrom, whereby the beverage may be allowed to flow naturally into the gas, obviating the excessive foam which is present in the ordinary method of drawing ginger-ale, because of the high pressure in the tank in which the ale is carbonated.

Located in the pipe Heading to the gascylinder is a gas-pressure regulator 21 of the ordinary type, by means of which any desired pressure in the keg may be maintained.

It will be understood that by the use of this apparatus a great saving of gas is accomplished, owing to the fact that it is used at such a greatly-reduced pressure from that ordinarily employed in ginger-ale-dispensing apparatus.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a device for the purpose set forth, the combination of a beverage-containing cask,

a gas-cylinder, a dispensing-faucet, a bung having a long sleeve integral therewith, said bu ng being adapted to be secured in the head of said cask with the sleeve depending vertically therein to a point adjacent the bottom of the cask so that its lower end is at all times submerged, an inner tube having openings at its lower end adapted to be passed centrally through said sleeve and secured by a compressible gasket within said bung, forminga gas passage-way between the inner wall of the sleeve and the outer wall of the tube which extends to the openings at the lower end of said tube, a pipe connecting said tube with the dispensing-faucet, and a pipe connecting the gas-cylinder with said gas passage-way.

2. The combination of a beverage-containing cask, a hung seated in the head of said cask and having an integral sleeve which depends therein to a point adjacent the bottom, an inner tube removably seated in said sleeve having apertures adjacent the lower end of the sleeve, and passing upwardly through said bung, forming a gas-space within said tube around said sleeve, a dispensing-faucet, a pipe connecting said inner tube with said faucet, a gas-cylinder and a pipe connecting said cylinder with the gas-space Within said bung and sleeve.

3. In an apparatus for the purpose set forth, the combination of a cask, a bung seated in the head of the cask and having an integral depending sleeve whose lower end extends to the bottom of the cask, a tube passing through said bung and sleeve, said tube having in its lower end apertures formed therein on a plane with the lower end of said sleeve, a gas-chamber within said bung and a gas passage-way within said sleeve around said tube communicating with said gas-chamber, a gas-cylinder, a pipe connecting the gas-chamber with said cylinder, and a pipe connecting said tube with a draft-faucet.

In testimony whereof I sign this specification in the presence of two witnesses.

AUSTIN R. PHILLIPS.
